Fix CRM load test setup path drift in ci-cd pipeline

Summary

ci-cd-crm fails in the loadTests batch on main because the infrastructure repo still prepares k6 config under crm/src/test/load, while the CRM repository stores load-test assets under crm/tests/load.

Evidence

• Prod pipeline: ci-cd-crm-prod-pipeline
• Execution: 4af664ae-5b20-4200-9fb5-82d8ec02e26f
• Failed child build: ci-cd-crm-prod-batch-pw-load:b63740b0-974f-40e9-ab71-b962641e8d9b
• Infra script: aws/scripts/sh/k6_installation.sh
• Current incorrect paths:
  • crm/src/test/load/config.json.dist
  • crm/src/test/load/config.json
• Actual CRM repository paths:
  • crm/tests/load/config.json.dist
  • crm/tests/load/...

Expected

• k6_installation.sh should prepare load-test config from the actual CRM repository layout.
• ci-cd-crm should pass on test and prod from main.

Acceptance criteria

• aws/scripts/sh/k6_installation.sh handles the CRM load-test directory correctly
• GitHub CI is green
• CodeRabbit approves the PR
• ci-cd-crm-test-pipeline succeeds from main
• ci-cd-crm-prod-pipeline succeeds from main
